To update using the official manual:
https://www.openproject.org/operations/upgrading/upgrade-guide-manual-installation/

Stage one:
[openprojectdebian]# cd /home/openproject/openproject
[openproject@debian]# git fetch && git checkout stable/7@

As a result, I get the error:
~/openproject-ce$ git fetch && git checkout stable/7 M Gemfile M frontend/npm-shrinkwrap.json Already on 'stable/7' Your branch is behind 'origin/stable/7' by 32639 commits, and can be fast-forwarded. (use "git pull" to update your local branch)

Well, do the following:
~/openproject-ce$ git pull Updating 7de7cda046..ef02b087c8 error: Your local changes to the following files would be overwritten by merge: Gemfile frontend/npm-shrinkwrap.json Please commit your changes or stash them before you merge. Aborting

Well, do the following:
~/openproject-ce$ git commit On branch stable/7 Your branch is behind 'origin/stable/7' by 32639 commits, and can be fast-forwarded. (use "git pull" to update your local branch) Changes not staged for commit: modified: Gemfile modified: frontend/npm-shrinkwrap.json Untracked files: package-lock.json v4.2.2 vendor/ no changes added to commit

Please tell me how to do the update manually?

You have made local modification to your Gemfile and frontend/npm-shrinkwrap.json, which is why git pull is rejecting to apply changes.

If you’re certain you do not need these modifications, use

git fetch
git reset --hard origin/stable/7

If you want to keep these modifications (Please note that modifying your Gemfile will likely cause merge conflicts you’ll have to resolve), commit your changes, then git pull origin stable/7.

Best,
Oliver

Why aren’t you using the installation packages?

Thank you so much! It’s all good! I’m happy! :-)

Historically the situation. Had problems with installation of version 6 in Debian, so I had to install it manually.
